Fix login problems in under 10 minutes
Start with basic checks: confirm your username and password, ensure a stable internet connection, and update the app to the latest version. On mobile, force-close and clear the app cache; on desktop try a private window to rule out browser extensions.
- Reset the password from the login screen and choose a new strong password.
- Temporarily disable VPNs or proxies—regional blocks can interfere with authentication.
- Verify device date/time and any two-factor authentication prompts before retrying.
If app updates fail, reinstall but back up any saved data first. For repeated failed attempts, wait the cooldown period to avoid extended lockouts. The screenshot below shows where common settings live.
